Hello.

 

I have read the topic "U-Boot and MMC/SDIO" (http://docs.blackfin.uclinux.org/doku.php?id=bootloaders:u-boot:mmc), compile U-Boot from source code. I plane to connect SD card to my board through SPI, but I can not find commands 'mmcinit',  'fatinfo', 'fatls', etc.

 

From what can I start?

you need to enable the options in the board config and rebuild u-boot.  the bf533-ezkit doesnt have any of these enabled by default.

Of course, I understand it. But where can I read topic about configuration? I read "Porting U-Boot To Your Board", but there is nothing about it. What exactly need to be changed? I see file u-boot/include/config/bf533-ezkit.h but not find according items.
